Abstract

1 / 1 resumo “dispositivo e mã‰todo de processamento de imagem” a descriã§ã£o presente relaciona-se a um dispositivo e mã©todo de processamento de imagem que torna possã­vel melhorar a eficiãªncia de codificaã§ã£o de codificar e decodificar um vetor de movimento em uma imagem de multivisã£o. quando o ref poc (ref 0) de uma pu atual e o ref poc (ref 0) de uma pu de referãªncia em uma visã£o diferente diferem entre si, um vetor de movimento da pu de referãªncia ã© graduado e usado como um candidato para um vetor de prediã§ã£o da pu atual. isto ã©, um vetor de prediã§ã£o (pmv l0) da pu atual e um vetor de movimento (mvl0) da pu de referãªncia diferem entre si em ref poc. portanto, o vetor de movimento (mvl0) da pu de referãªncia ã© graduado de acordo com o ref poc, e o vetor de movimento graduado (mvl0) ã© usado como um candidato para um vetor de prediã§ã£o da pu atual. a descriã§ã£o presente ã© aplicã¡vel a, por exemplo, dispositivos de processamento de imagem.1 / 1 abstract “image processing device and method†the present description relates to an image processing device and method that makes it possible to improve encoding efficiency to encode and decode a motion vector in a multiview image. when the ref poc (ref 0) of a current pu and the ref poc (ref 0) of a reference pu in a different view differ from each other, a motion vector of the reference pu is scaled and used as a candidate for a prediction vector of the current pu. that is, a prediction vector (pmv l0) of the current pu and a motion vector (mvl0) of the reference pu differ from each other in ref poc. therefore, the motion vector (mvl0) of the reference pu is graded according to the ref poc, and the graded motion vector (mvl0) is used as a candidate for a prediction vector of the current pu . the present description is applicable to, for example, image processing devices.
